The Mailing List is an opt in type, meaning that when someone adds their
email address to the list, they are sent a confirmation email containing
a link with an access code. Unless they click the link, their email
address will not be added to the list. The opt-in link will expire in 48
hours. Conversely, when someone in your mailing list receives an email,
there will be an “unsubscribe” link permitting them to remove themselves
from the list.

Note

The Mailing List Module is available only with a
purchased ExpressionEngine license.

To access the Mailing List-backed functions, go to Add-
Ons ‣ Modules ‣ Mailing List in your Control Panel. There you will
be able to create and manage your mailing lists, as well as find and
delete email addresses. See Mailing List control panel for more information. To
send email to any of your lists you will use the Control Panel
Communicate Page.

This parameter allows you to specify which Mailing List the email
address will be subscribed to. This parameter takes the “short name” of
the List as set in the Mailing List control panel. If no list is
specified with the parameter then the “default” list is assumed.
